My original lid broke after a year, and this replacement is exactly like the original. It fits perfectly and works great. The two extra straws are a bonus. Highly recommend if you need a new lid.
The lid fits my Hydro Flask perfectly and is leakproof. However, the included straws were too long for my bottle, and I had to cut them. That's easy to do, but I wish they were pre-cut. The color is nice.
I lost my original straw cap and this replacement is perfect. It fits my Hydro Flask wide mouth bottle perfectly, and the straws are easy to cut to size. The capri blue color matches my bottle. It's leakproof and works as expected. Great value for the price.
The lid works well and fits my bottle, but I noticed it's slightly different from the original – the straw is a bit stiffer. But it functions fine. The two straws included is nice. Overall, satisfied.
I bought this as a backup lid, and it's just as good as the original. It's easy to clean, and the silicone gasket keeps everything tight. The included straws are a nice addition. Would buy again.
The replacement lid fits, but it doesn't feel as secure as the original. There's a slight wobble, and I'm worried about leaks if I tip it over. I tested it with water and it didn't leak, but it's not perfect. The straws are fine.
I have two Hydro Flasks and needed extra straws. This replacement lid fits both perfectly. The straws are long, but I trimmed them to my liking. The color is vibrant. It keeps the bottle leakproof. Very happy.
This replacement lid is fine, but the straw is softer than the original. That's actually okay, because it doesn't poke my mouth. It fits well and doesn't leak. The two straws are a good bonus. I'd recommend it.
I've been using this replacement lid for a month and it works flawlessly. It fits my 24 oz bottle perfectly and keeps water cold. The straw is comfortable to drink from. The capri blue is pretty. Great value for the price.
The lid works well and is leakproof, but the straw is a bit short – it doesn't quite reach the bottom of my bottle. I have to tilt the bottle to get the last few sips. But that's a minor issue. Overall, good value.
I replaced my original lid with this one because I prefer straws. It fits perfectly, is easy to clean, and doesn't leak. The two straws are a nice touch. Highly recommend.
